The MRTA is reviewing all five regional rail projects (Chiang Mai, Phuket, Korat, Phitsanulok, Songkhla) and has no firm start year. Chiang Mai's Red Line, Phuket phase 1 and Korat's Orange Line are expected to move first, with the least state subsidy going first. Phuket's bus EV trial is already running privately. Hat Yai (Songkhla) targets approval around 2028, construction around 2031 and opening around 2035 under the article's schedule. For a small business, this is long-range: consider site decisions near planned stations in Chiang Mai, Phuket or Korat, but no action is needed this quarter.
